ng g input.mergeMap is not a function

[dottodot]

ng g app-shell works on a fresh app but on my project I get the following error but no idea what it means

TypeError: input.mergeMap is not a function
    at Object.callRule (/node_modules/@angular-devkit/schematics/src/rules/call.js:70:18)
    at SchematicImpl.call (/node_modules/@angular-devkit/schematics/src/engine/schematic.js:35:23)

The only thing I can think of is it's a multi app setup structured like

src
  -- client
      -- app
  -- admin
      -- app
  -- environments

but I've tried setting the root and get the same result

ng generate app-shell [ --universal-app universal --root src/client ]

Same happens with ng g component [componentname] or ng g module [modulename]

ng generate module public-library/trial

Ok so deleting node_modules and reinstalling seems to clear that error but faced with a new error of

Error: Specified module does not exist
Specified module does not exist

[njifares]

Same issue here after updating CLI from 1.5.2 to 1.6.0

[cristianqr]

The same is happening with:
ng generate module module-name

I think the issue is with all commands of angular cli.

[Brocco]

If you are receiving an error other than Specified module does not exist please create a new issue with your error and steps to recreate.

It seems that if you have @angular/cli installed globally and a different version installed locally it gets broken.
I solved the same error removing the cli package that was installed locally with npm remove @angular/cli --save in my project folder.

Both my global and local version are the same.

But.... uninstalling the local (project) cli works. 👍

[edit]
The other way around => uninstall global and install local project CLI results in the same error.
So it seems to be a problem with the local (project) cli

[oldlie]

Removing local @angular/cli can resolve this issue, but globally CLI can't add automatically the references to the related local ts files.
